Triple Expressor Lymphoma: Presentation With Acute Paraparesis Due to Spinal Cord Compression

Diffuse large B-cell lymphoma (DBLCL) is the most common type of non-Hodgkin's lymphoma (NHL). Triple expressor lymphoma is a subgroup of non-Hodgkin's lymphomas that exhibits simultaneous overexpression of the MYC, BCL2, and BCL6 genes. This entity is characterized by its aggressive behavior and its poor response to chemotherapy regimens traditionally used, such as the standard R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) regimen. This neoplasm can have varied clinical manifestations according to its initial location and usually has central nervous system (CNS) involvement. This article presents the case of a triple expressor lymphoma with spinal involvement at the level of the thoracic vertebrae in a previously healthy 34-year-old female patient, which lead to acute paraparesis due to spinal cord compression. Nevertheless, appropriate treatment with the DA-EPOCH-R (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab) regimen resulted in the recovery of the motor and sensory function of the lower extremities.
